"Mr. Macgregor," said the old man, taking Shock by the hand, "I have found that life sooner or later brings opportunity to discharge every obligation. Such an opportunity I shall eagerly await."

"I have done no more than any man should," replied Shock simply. "And I am only glad to have had the chance."

"Chance!" echoed the Old Prospector. "I have found that we make our chances, sir. But now you will require lodging. I regret I cannot offer you hospitality. Perault, go down to the Stopping Place, present my compliments to Carroll and ask him to give Mr. Macgregor the best accommodation he has. The best is none too good. And, Perault, we shall need another pony and a new outfit. In a few days we must be on the move again. See Carroll about these things and report. Meantime, Mr. Macgregor, you will remain with us to tea."

"Carroll!" exclaimed Perault in a tone of disgust. "Dat man no good 'tall. I get you one pony cheap. Dat Carroll he's one beeg tief."

The little Frenchman's eyes glittered with hate.

"Perault," replied the Old Prospector quietly, "I quite understand you have your own quarrel with Carroll, but these are my affairs. Carroll will not cheat me."

"Ah! Bah!" spat Perault in a vicious undertone of disgust. "De ole boss he blam-fool. He not see noting." And Perault departed, grumbling and swearing, to make his deal with Carroll.

Timothy Carroll was a man altogether remarkable, even in that country of remarkable men. Of his past history little was known. At one time a Hudson Bay trader, then a freighter. At present he "ran" the Loon Lake Stopping Place and a livery stable, took contracts in freight, and conducted a general trading business in horses, cattle—anything, in short, that could be bought and sold in that country. A man of powerful physique and great shrewdness, he easily dominated the community of Loon Lake. He was a curious mixture of incongruous characteristics. At the same time many a poor fellow had found in him a friend in sickness or "in hard luck," and by his wife and family he was adored. His tenderness for little lame Patsy was the marvel of all who knew the terrible Tim Carroll. He had a furious temper, and in wrath was truly terrifying, while in matters of trade he was cool, cunning, and unscrupulous. Few men had ever dared to face his rage, and few had ever worsted him in a "deal." No wonder Perault, who had experienced both the fury of his rage and the unscrupulousness of his trading methods, approached him with reluctance. But, though Perault had suffered at the hands of the big Irishman, the chief cause of his hatred was not personal. He knew, what many others in the community suspected, that for years Carroll had systematically robbed and had contributed largely to the ruin of his "old boss." Walter Mowbray was haunted by one enslaving vice. He was by temperament and by habit a gambler. It was this vice that had been his ruin. In the madness of his passion he had risked and lost, one fatal night in the old land, the funds of the financial institution of which he was the trusted and honoured head. In the agony of his shame he had fled from his home, leaving in her grave his broken-hearted wife, and abandoning to the care of his maiden sister his little girl of a year old, and had sought, in the feverish search for gold, relief from haunting memory, redemption for himself, and provision for his child. In his prospecting experiments success had attended him. He developed in a marvellous degree the prospector's instinct, for instinct it appeared to be; and many of the important prospects, and some of the most valuable mines in Southern British Columbia, had been discovered by him.

It was at this point that Carroll took a hand. Acting in collusion with the expert agent for the British American Gold and Silver Mining Company, he had bought for hundreds of dollars and sold for thousands the Old Prospector's claims. Not that the old man had lost that financial ability or that knowledge of human nature that had given him his high place in former days, but he was possessed of a dream of wealth so vast that ordinary fortunes shrank into insignificance in comparison. He had fallen under the spell of an Indian tale of a lost river of fabulous wealth in gold that disturbed all his sense of value. In one of his prospecting tours he had come upon an old Indian hunter, torn by a grizzly and dying. For weeks he nursed the old Indian in his camp with tender but unavailing care. In gratitude, the dying man had told of the lost river that flowed over rocks and sands sown with gold. In his young days the Indian had seen the river and had gathered its "yellow sand and stones"; in later years, however, when he had come to know something of the value of this "yellow sand and stones" he had sought the river, but in vain. A mountain peak in one vast slide had filled up the valley, diverted the course of the river, and changed the whole face of the country. For many summers the Indian had sought with the unfaltering patience of his race the bed of the lost river, and at length, that very summer, he had discovered it. Deep down in a side canyon in the bed of a trickling brook he had found "yellow sand and stones" similar to those of the lost river of his youth. As the dying Indian poured out from his buckskin bag the glittering sand and rusty bits of rock, there entered into the Old Prospector the terrible gold-lust that for thirteen years burned as a fever in his bones and lured him on through perils and privations, over mountains and along canyons, making him insensible to storms and frosts and burning suns, and that even now, old man as he was, worn and broken, still burned with unquenchable flame.

Under the spell of that dream of wealth he found it easy to pay his "debts of honour" to Carroll with mining claims, which, however valuable in themselves, were to him paltry in comparison with the wealth of the Lost River, to which every year brought him nearer, and which one day he was sure he would possess. That Carroll and his confederate robbed him he knew well enough, but finding Carroll useful to him, both in the way of outfitting his annual expeditions and in providing means for the gratifying of his life-long gambling passion, by which the deadly monotony of the long winter days and nights was relieved, he tolerated while he scorned him and his villainy.
